- matic pistol, for instanoe,'a trigger, a scar,

and a magazine, and in conjunction with these arts 1' provide a novelreceiver con struct on, breech'block, and firing member, the last twoelementsbeing' compactly arranged within the receiver to cooperate inautomatically reloading and discharging the pistolby the control of thetrigger.

Considering the detail construction of the pistol, the referencenumeral- 1 denotes a pistol body or frame having a receiver 2, a hollowhandle 3 in communication with said receiver and adapted to contain amagazine 4, and a-barrel 5 having the rear end thereof extending intosaid receiver and. formed 1ntegral' with the-side wall 6 thereof, .Therear end of the barrel 5 extends into the receiver 2 approximately halfthe length of said receiver and forms .a chamber 7 to receive acartridge from. the magazine 4. The rear end of the barrel 5-prov1des alongitudinal guideway 8 in the upper part of the receiver and anotherguidewa 9 1n the lower part of the receiver, the ormer accommodating afiring member and the latter a breech block.

The breech block comprises an oblong body 10 having the top thereofprovided with a Y longitudinal roove 11 and the'bottom thereof withlongitudinal grooves 12, the latter being provided to establishcommunlcatlon between the cartridge chamber 7 of the barrel '5 and thelower part of the receiver 2 and the hollow handle 3, thus providingmeans-whereby the ases can easil escape er the pistol as beendischarged. The grooves 12 also reduce the weight of the breech block.One of the tudinal ribs 13 and a longitudinal groove '14. Pivotallymounted in the groove 14 walls of the body 10 is'provi'ded withlongiribs 13 is an extractor 16. One end of the and retain the sameagainst the end 0 extractor projects beyond the end of the. body and ishookshaped or prov ded with a' tooth -'17 to engage the rim of acartildge 0 body during the rearward movement thereof, The opposite endof the extractor is" spring-pressed by acoiled spring 18 mounted in thegroove 1 The forward end of the body is provided with a longitudinal pinopening 19 and with a forwardly projecting yoke or cage 20, this i yokebeing off-set with the upper edge thereof in longitudinal alinement withthe lower side of the body 10. The forward end of the yoke 20 isprovidedwith a pin openmg 21 and with a depending guide lug 22. The rear end ofthe body 10 is provided wlth a knob or' suitable handle 23 whereby thebreech block can be easil manipulated.

The wall 6 of the pistol body has the inner side thereof provided with alongitudinal guide groove 24 for the body 10 of the breech block, saidgroove extending from the rear end of the barrel 5 to a slot 25 formedin the rear end of the body 1, said slot accommodating the rear end ofthe breech block. The wall 6 is further grooved,

as at 26 to provide clearance for the ribs 13 and the extractor 16 ofthe breech block, and at the forward ends of the ooves 24 and 26 thewall 6 is provided with an oblong opening 27 for the ejection ofcartmdge shells, said opening being in comunication with the transverseslot 28 formed in the rear end of the barrel 5 and in the wall 6 toprovide clearance for the toothed end 17 of the extractor 16. The lowerpart of the groove 24 extends into the guideway 9 of the receiver, as at29 and provides a guide for one of the arms of the yoke 20' of thebreech block.

Arranged in the yoke 20 of the breech block is a longitudinal pin 30,having the rear end thereof provided with a head 31 and the forward endthereof with a head 32. The forward end of the pin extends through theopening 21 of the yoke .20 and seats in a socket 33 provided therefor inthe forward end of the body 1 directl beneath the barrel 5, the head 32of sai pin anchoring the pin whereby the breech block can be independentof said pin. Encircling the pin 30 between the head'31 and the end ofthe yoke 20 is a coiled retractile sprin 34 adaptedto normally retainthe forwar end of the breech block 10 in'engagement with the rear end ofthe barrel 5.

The-firing member used in connection with the breech block comprises anoblong body 35 having the rear end thereof provided with a depending lug36 and the forward side of this lug is provided with a longitudinallydisposed firing pin 37 adapted to enter the opening 19 at the-forwardend of the breech block body 10. The forward end of the body 35 at oneside thereof is provided with a dependingv strap 38 to partially embraceandslide upon the side of the barrel 5 at the rear end thereof. Thisstrap extends downwardly in the yoke 20 and adjacent to said yoke is ashoulder 39 for a purpose that will presently appear. The lower end ofthe strap 38 is below the yoke 20 and is provided with a right-angularextension 40 adapted to be engaged 37 L within the opening 19 of thebreech block, said spring being held under tension when in a cocked orrearward position and held by the sear of the trigger mechanism.

The pistol body 1 at its uncture with the hollow handle 3 .is providedwith a trigger guard 44 and with an'opening 45. Pivotally mounted in theopening 45 by a transverse pin 46 is a trigger body 47 having adepending curved trigger 48 withinthe ard 44. The trigger body 47 isprovided with a spring-pressed sear actuating member 49 held- 1nengagement with a sear 50 pivoted in the receiver 2 by a transverse pin51. The sear is provided with a tooth 52 normally held in engagementwith the right-angular extension 40 of the firing member by a spring 53mounted in the receiver 2. A spring 54 mounted in the forward end of theguideway 9 normally retains the trigger body 47 in a osition that thesear actuating member 49 t ereof will engage the lower end of the sear50.v

The hollow handle 3 of the pistol body has the rear wall 55 thereofhinged at its upper end, as at 56, whereby the magazine 4 can be easilyplaced in the hollow handle. Thelower end of the wall 55 is held in aclosed position by a resilient clasp mounted in the lower end of thehollo handle. The magazine 4 comprises a shell having the wall thereofprovided with a longitudinal slot 71 and slidably mounted insaid 'slotis the button 72 of a cartridge feeding device 58, this device includinga compression spring 73, a feed spring 74, and a gate 75. The button 72permits of the cartridge feeding device being lowered within themagazine when the same is to be loaded with cartridges. The magazineisprevented from rattling or shifting within the hollow handle 3 by aspring 59 secured to the inner upper side of the'wall 55 of the hollowhandle, said magazine being further held by a small pin 60 extendinginto the magazine near the 4 lower end thereof The pistol body isprovided with a detachable side plate 61 held in engagement with thebody by screws or other fastening means 62. The plate 61 has the upperpart thereof off-set to provide a guide groove 63 for the strap 38 ofthe firing member and the'yoke 20 of the breech block, said side "platehaving a longitudinal rib 64 that engages the shoulder 39 of the strap38 and asslsts in supporting the same during its longitudinal movement.The side plate 61 adjacent to the trigger mechanism is provided with asafety device comprising a crank shaft 65 having the outer end thereofprovided with a small button or lever 66. The crank shaft 65 is adaptedto engage under the spring 53 and lock the sear 50 in engagement withthe right-angular extension lO of the firing member, thus preventing thesear iroin bemg moved out of engagement with handle 3 and the side saidright-angular extension by a movement of the trigger. Suitable plates 67can be mounted upon the outer side of the hollow plate 61 to provide-ahand-grip. I

A pistol in accordance with this invention is-operated in the followingmanner :-Assuming that the magazine 4 has been loaded and placed in thehollow handle, the upper most cartridge will be held against the underside of the breech block; the breech block is pulled rearwardly by handand the first cartridge is immediately released from the magazine andwhen the breech block is released, the cartridge is carried into thechamher 7 of the barrel 5, with the rim of said,

' lar extension 40 of the firing member is engaged by the sear and heldwith the firing member'in a firing position. When the trigger 48 ispulled the sear 50 is shifted to release the right-angular extension 40of the firing member and the tension of the spring 43 immediately movesthe firing member forward with such force that the firing pin 37 willfire the cartridge within the chamher 7 The breech block is manuallypulled rearwardly in order to load the first cartridge, but whenthis-cartridge is-fired the pressure of gases drives the breech blockrearward I hausted of cartridges.

and the pistol is immediately reloaded by the feeding mechanism of themagazine 4 and the breech block. For repeated. firing it is onlynecessary to retain the finger upon" the trigger48 until the magazine 4is ex- At each rearward movement of the breech block the cartridge shellis removed from the chamber of the barrel and ejected from the pistol.

From the foregoing it will be observed that I have devised afirearmembodying a receiver havinga' barrel projecting there-' in, a breechblock normally he d in engagement'with the end or" the pro ectingbarrel,
